Preferences window doesn't work fine

[Vicente Ruiz]

I downloaded the project and I was running it. When I open Preferences window, it shows the following output:

$ python fridgemonitor.py
A new WindowEvents has been created
Traceback (most recent call last):
  File "fridgemonitor.py", line 62, in preferences_cb
    window_pref = gui.WindowPref()
  File "/home/vruiz/Desktop/fridgemonitor-0.3/gui.py", line 33, in __init__
    SimpleGladeApp.__init__(self, path, root, domain, **kwargs)

    cfg.read(["cfg"])

In the last upload (rev 7) the window is shown again, but still non functional.
